More about ThirdEye

The functionality of the ThirdEye information stealer is fairly straightforward. It collects system information from compromised machines, including BIOS and hardware details. Additionally, it scans for files, folders, running processes, and network information. ThirdEye transmits gathered data to its designated Command-and-Control (C2) server.

The system information obtained from compromised machines, including BIOS and hardware details, can be used by cybercriminals for various malicious purposes. By analyzing this information, they can identify vulnerabilities or weaknesses in the system, which can be exploited for unauthorized access or further compromise.

For example, knowledge of the hardware and BIOS version may help them target specific exploits or devise sophisticated attacks. In summary, cybercriminals can leverage obtained information to plan targeted attacks, gain unauthorized access, perform identity theft, or facilitate other malicious activities.

How did ThirdEye infiltrate my computer?

ThirdEye is spread through a ZIP file that contains two executable (.exe) files disguised as regular documents (PDF docs) by using additional file extensions. The ZIP file containing the ThirdEye malware can be distributed through various methods, including email attachments, malicious websites, file-sharing networks, or disguised as legitimate software downloads.

Cybercriminals may use social engineering techniques, such as phishing emails or deceptive websites, to trick users into downloading and opening the ZIP file's contents, unknowingly infecting their system with the malware.

How to avoid installation of malware?

Be cautious when opening email attachments or clicking on links, especially if they are from unknown or suspicious sources. Only download programs or files from reputable sources such as official websites or trusted app stores. Avoid downloading from shady websites or Peer-to-Peer networks, and similar sources, as they may contain malicious software.

Keep your operating system and all software up to date by installing the latest security patches and updates. Use reliable antivirus software and keep it regularly updated. Avoid clicking on suspicious ads or pop-ups, and be cautious when visiting unfamiliar websites. Stick to well-known and trusted websites to minimize the risk of encountering malicious content.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.
